| Abstract: | Nazixia Hydropower Project is with a concrete face gravel-fill dam. Currently, the embankment filling is fulfilled. During the embankment filling, the effective quality supervision system is established and implemented. Through the quality control of overburden excavation, material selection, unloading, spreading, water spraying, roller compaction, and measurement of dry intensity of the gravel materials for the main embankment, quality of the roller compaction of the embankment filling satisfy the design requirements. |
